简介:目的了解我院新生乙型肝炎病毒感染情况,以便采取必要的防治措施,减少和控制乙肝的传播和流行。方法对绵阳师范学院2005级3700名新生测定HBsAg,对HBsAg阳性的学生用ELISA法进行乙肝5项标记物的测定。结果HBsAg总体阳性率5.32%,低于全国平均水平,以不同民族来看,汉族HBsAg出率为5.50%,少数民族为1.74%,两者比较有统计学意义;以性别来看,男生HBsAg阳性率为6.48%,女生为4.80%,两者比较有统计学意义;且以“大三阳”和“小三阳”两种感染类型为主。结论高校应做好新生入学时乙肝的防治工作,进行乙肝防治知识的健康教育,加强传染源管理,对易感者进行乙肝疫苗接种。
